Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a pickle container that enables the production of pickles, and particularly relates to a pickle container that improves the airtightness of the pickle container to prevent odor leakage.

[Prior Art] Equipment for easily making pickles at home includes a cylindrical container with a bottom for storing vegetables, etc.
It consists of a container lid that closes the opening of the container, and a push rod that pressurizes vegetables, etc. to the push lid, which is screwed onto a female screw formed at the axis of the container and housed in the container. There are known devices that adjust the .

However, the above-mentioned Tsukemono container does not have a seal at the engagement part between the container, the container lid, the push rod, and the female thread, which causes the odor generated inside the container to leak out of the container. It is necessary to adjust the degree of dipping by adjusting the amount of advance of the push rod each time.If a structure is adopted in which the degree of dipping is adjusted using a screw structure, the reaction force of the screw will be applied to the joint between the container and the container lid. There are problems such as the possibility that the container or container lid may be damaged due to the action. Therefore, as shown in FIG.
and a container lid b that seals and covers the entrance of this container a.
a pickle container comprising: a push-cover c that substantially contacts and covers the upper surface of the vegetables, etc. in the container a; and a seal d that seals the engagement surface between the container lid b and the container a. is proposed.

According to this proposal, there is an advantage that the weight of the lid c can be kept the same at all times, and that the gasket d can completely block the leakage of odors generated inside the container to the outside. In addition, in the proposal, in order to improve the sealing performance between the container a and the container lid b, a latch e is used to apply a pressing force to the container a and the container lid b, causing the seal d to elastically deform, thereby sealing the entrance of the container a. and is configured to prevent odor from leaking out of the container a.

[Problem to be solved by the invention] In the above proposal, it is necessary to operate the latch e when attaching and removing the container lid b, but the operation of the latch e requires a large operating force for women. The problem is that it becomes complicated and complicated.

As a related technique, Japanese Utility Model Publication No. 8227/1983 discloses a method in which a reinforcing part having a U-shaped cross section is provided on the outer peripheral surface of the upper part of a container for accessories and projects outward in the radial direction so as to cover the container in a hermetically sealed manner. A flexible lid made of synthetic resin is provided with an inverted U-shaped fitting part around the peripheral edge of the lid, which tightly engages with the reinforcing part due to the high elasticity of the lid. A pickle container has been proposed in which the seal is achieved through close contact with the joint, but this structure requires high elasticity in the lid to improve the seal, making it unsuitable for housewives. It is.

[Means for solving the problem] The first idea includes a pickled vegetable container with an open top, a container lid that tightly covers the pickled vegetable container,
A container fitting portion provided to frame the peripheral edge of the container lid in a cylindrical shape; and an inner surface on the peripheral edge side of the container lid provided to frame the upper outer peripheral surface of the container. an annular protrusion integrally provided on the inner surface of the peripheral edge of the container lid; an elastic packing interposed between the inner surface of the container lid and the lid seating surface, a packing fixing groove provided on the lid seating surface to securely fit the elastic packing, and the engaging a locking part having a semicircular cross section and a locking part having a semi-circular cross section, which is provided so as to protrude outward in the radial direction along the circumferential direction; When the pressing force for fitting the container lid is applied, the outer surface of the locking portion slides from above to the bottom and wraps around the lower surface of the locking portion, and the annular projection is integrated with the container while integrating the container lid with the container. It is equipped with a hemispherical engagement piece that bites into the elastic packing.

The second idea is to apply the weight of the weight housed in the container and the push rod that is movably guided and sealed to the container lid to act on the push lid housed in the container lid in the first idea. A cylindrical guide tube part for guiding the push rod in a vertically movable manner is integrally provided on the container lid, and a seal is formed by slidingly contacting the inner surface of the guide tube section with the outer surface of the push rod to block odor leakage inside the container. The members are provided in a pleated shape.

A third invention is based on the second invention, and is provided with a removable opening/closing plug which is screwed onto the outer surface of the cylindrical part and seals the cylindrical part when the push rod is removed. .

[Function] First, to describe the function of the first device, when the container lid is fitted into the engaging portion formed on the top of the container and a pressing force is applied to the container lid, the hemispherical engaging portion on the inner surface of the container fitting portion is pressed. Each piece independently slides (slides) on the locking portion, climbs over the locking portion, and wraps around the lower surface of the locking portion. At this point, the container lid is locked to the locking portion, and the annular projection bites into the elastic packing. At this time, the elastic packing, whose protrusion and movement are restrained by the packing fixing groove, has both radial end edges raised up and in close contact with the inner surface of the container lid. In other words, the elastic packing remains flat and tightly adheres to the inner surface of the container lid with a predetermined sealing force. As a result, the part where the annular protrusion bites,
A high sealing force is generated between the packing fixing groove and the elastic packing, and between the upper surface of the elastic packing and the inner surface of the container lid. Therefore, compared to the case where an elastic packing is simply interposed between the inner surface of the container lid and the lid seating surface, a much higher sealing function is produced, and no odor leaks from inside the container. When removing the container lid from the container, if the container lid is opened appropriately in the radial direction, the engaging piece will naturally separate from the locking portion.

Since the hemispherical engaging pieces are each independent in the circumferential direction and slide on the locking portion, even women can easily lock the container lid to the dipping sauce container.

In this way, the present invention does not attempt to airtightly fit the reinforcing part and the fitting part to create a seal between them like the pickle container proposed in Publication of Utility Model Publication No. 63-8227. By fitting the elastic packing into the packing fixing groove and biting the annular projection into the elastic packing, the sealing force of the elastic packing is significantly increased. While engaging, a large sealing force is generated as a result.

The second idea produces the following effects in addition to the above effects. That is, when the push rod is attached to the guide cylinder portion of the container lid so as to be able to move up and down, the push rod applies the weight of the weight to the lid and pressurizes the vegetables, etc. in the container. At this time, the reaction force of the push rod does not act on the container lid because the push rod can move up and down with respect to the guide tube. In other words, the locked state between the locking portion and the locking piece is maintained. The sealing member provided on the inner surface of the guide tube is
When the push rod is raised and lowered, it falls down along the sliding direction of the push rod to reduce the sliding resistance of the push rod while maintaining a constant sealing ability. As a result, it becomes extremely easy to insert and remove the push rod, and odor leakage from between the push rod and the guide tube portion is prevented.

In other words, the pleated sealing member according to the present invention, unlike the grommet-like sealing member commonly available on the market, achieves high sealing performance while significantly reducing sliding resistance.

The third invention takes into account the following points in the second invention. In other words, the object of the dressing is
There is no need to use weights for miso-zuke, Narazuke, eggplant, and pickled cucumbers in rice bran, so in such cases, you can eliminate odors by simply removing the weights and push rods and screwing the opening/closing stopper onto the outside of the guide tube. Block external leakage.

[Example] (Example 1) A first example of this invention will be described below based on FIGS. 1 and 2.

1 shown in FIG. 2 is a pickle container formed in the shape of a cylinder with a bottom, and the upper opening edge 2 of this pickle container 1 is
A lid seating surface portion 3 is provided horizontally so as to frame this upper opening edge 2. On the other hand, the container lid 5, which is formed so as to close the inlet 6 of the container 1 by having its inner surface on the peripheral edge side seated on the lid seating surface 3, has an inner surface on the peripheral edge of the horizontal lid main body 7. A container fitting portion 8 is integrally provided so as to frame the peripheral edge in a cylindrical shape. 7a is a rib for improving the rigidity of the container lid.

Between the inner surface of the container lid 5 and the lid seating surface 3, there is provided a material for completely sealing the space between the inner surface of the container lid 5 and the lid seating surface 3 when the lid is seated on the lid seating surface 3 and is brought into close contact with the lid seating surface 3. Ring-shaped elastic packing for food 9
is provided. At the axial center position of the container lid 5, there is a guide tube 10 that is raised in a convex shape inside and outside the container lid 5 to guide a push rod (described later) in a vertically movable manner.
are integrally provided. At the axial position of the guide tube 10, there is an opening 11 along the axial direction of the container lid 5.
An annular ring groove 12 is formed on the inner surface of the opening 11 by recessing it radially inward. A food groove seal ring 13 is fitted into the ring groove 12 to prevent the odor inside the pickles container 1 from leaking out of the pickles container 1. A push rod 14 having a somewhat smaller diameter and a spherical insertion end (tip) 16 is fitted so as to be movable up and down. In this embodiment, the push rod 14 is formed from a hollow shaft, and a spherical member 15 is integrally attached to the tip thereof. Inside the pickles container 1, the insertion end 16 of the push rod 14 is rotatably engaged at the upper axial center position.
A push rod 17 formed to evenly press the vegetables and the like inside is housed. In other words, the push lid 17
The press rod 14 tilts moderately to the pressurized surface of the vegetables stored in the pickled vegetable container 1 to evenly pressurize the vegetables, etc., so that the vegetables, etc. are evenly pickled by osmotic pressure. The diameter of the pickle container 1 is smaller than that of the inlet 6 thereof. The weight receiving seat 18 is the weight receiving seat 18.
It is formed into a tub shape so that a plurality of weights 19 can be placed one on top of the other. In other words, this weight receiving seat 18 is the weight 1 inside the weight receiving seat 18.
By changing the number of pickles, the degree of pickling can be adjusted freely, and the pickling time and preference can be adjusted as desired. In addition, the above weight 19
Of course, it is possible to form them to have the same weight or to have different weights, and if the material is hygienic, easy to clean, and has a large specific gravity (for example, polyethylene filled with mortar), It may be formed of any material.

Now, the purpose of this invention is to
The container lid 5 can be easily locked with a small force, and the gasket 9 can perform a certain sealing function after locking.
Therefore, the pickle container 1 and the container lid 5 are constructed as follows.

As shown in FIG. 1, an engaging portion 50 for engaging the container fitting portion 8 is provided so as to frame the outer peripheral surface of the lid seating surface portion 3 in a cylindrical shape. Upright portions 26 and 27 are formed so as to border both ends in the radial direction in a rib shape. In other words, these raised portions 26 and 27 constitute a gasket fixing groove 28 in which the base side of the gasket 9 is integrally fitted and fixed without movement. A locking portion 21 is formed on the outer circumferential surface 24 of the engaging portion 50 so as to protrude in the radial direction and has a semicircular cross section along the circumferential direction. Hemispherical engagement pieces 22 are formed on the inner surface 25 at predetermined intervals in the circumferential direction. The locking portion 21 and the engagement piece 22 are
When no pressing force is applied to the container lid 5 for fitting the container lid, the engaging piece 22 is formed to simply rest on the upper part of the locking part 21, and the engaging piece 22 is formed to simply rest on the upper part of the locking part 21, When the pressing force for fitting the lid is applied, the engagement piece 22 slides over the locking part 21 and gets over it, and when it finishes climbing over, the locking piece 22 touches the bottom surface of the locking part 21. It is formed so that it goes around and is locked to the part.

On the other hand, on the inner surface of the container lid 5 on the peripheral edge side, an annular projection 23 having a semicircular cross section is provided along the circumferential direction at a portion located approximately in the center of the upper surface of the gasket 9. That is, by providing this annular protrusion 23, the container lid 5 can
The annular protrusion 23 comes to bite into the upper surface of the packing 9, and the sealing performance of the packing 9 is dramatically improved. Incidentally, a V- or U-shaped circumferential groove may be formed on the upper surface of the packing 9 in order to allow the annular projection 23 to bite into it well. At the lowest end of the container fitting part 8, there is a bending part 2 in the circumferential direction of the container lid 5 to make it easier for fingers etc. to catch the container lid 5 when removing the container lid 5.
9 is formed.

Next, the operation of the first embodiment will be explained.

As shown in FIG. 2, vegetables are stored in the container lid 5, a push lid 17 is installed on the top surface of the vegetables, and the container fitting part 8 of the container lid 5 is fitted into the engaging part 50 of the pickled vegetable container 1. Match. A push rod 1 is attached to the guide tube 10 in advance.
Insert 4.

Here, when a pressing force is sequentially applied to the edge of the container lid 5 in the circumferential direction, the annular protrusion 23 is pressed against the gasket 9.
The entrance 6 of the pickled vegetable container 1 is inserted into the pocket 9.
sealed by. At this time, the engagement piece 22 of the container lid 5 moves from above to below while contacting the semicircular outer surface of the locking part 21 due to the pressing force.
Finally, it climbs over this and goes around to the lower part of the locking part 21. As a result, the container lid 5 is locked to the pickled food container 1, the annular projection 23 remains wedged into the gasket 9, and the gasket 9 is brought into close contact with the annular projection 23 and the gasket fixing groove 28. For this reason,
The leakage of odor from inside the pickled vegetable container 1 is completely blocked. Here, since the engaging pieces 22 of the container lid 5 are provided at predetermined intervals in the circumferential direction, if pressing force is sequentially applied in the circumferential direction, each engaging piece 22 will move to the locking portion 21 with a small pressing force. can be overcome in sequence. A groove seal ring 13 seals the engagement surface between the guide tube 10 and the push rod 14.

In order to lock the container lid 5 with a small pressing force when pressed with the palm of the hand, the radius of the engaging piece 22 and the locking portion 21 may be adjusted in consideration of the elasticity of the lid seating surface portion 3.

As a result, the inside of the pickles container 1 is completely shut off from the outside, preventing odor from leaking outside the pickles container 1.
Divergence is completely prevented.

In this state, when an appropriate number of weights 19 are placed on the weight receiving seat 18 of the push rod 14, the pickled vegetable container 1
The weight of the weight 19 and the push rod 14 acts on the push lid 17 inside. The push rod 14 applies its weight to the push lid 17, and the push lid 17
Apply pressure evenly to vegetables, etc. inside. In other words, the weight 19 continues to apply the same pressing force to the vegetables etc. via the push rod 14 and push lid 17 even if the degree of pickling of the vegetables etc. changes. Therefore, the degree of pickling is determined simply by adjusting the number of weights 19, and vegetables etc. are gradually pickled due to osmotic pressure. Moisture generated during the production process escapes to the upper part of the press lid 17. As long as the number of weights 19 is kept constant, the degree of pickling is uniquely determined by the pickling time.

In the embodiment, the lid seating surface portion 3 and the engaging portion 50 constitute a border portion. The materials constituting the pickle container 1, the container lid 5, the push rod 14, and the push lid 17 are made of a corrosion-resistant light metal material, glass, or high-density polyethylene resin material. Furthermore, the weight is displayed on each weight 19,
The total weight of the weights 19 for the types of vegetables, etc. on the container lid 5 and pickle container 1 (indication of the weights 19 (indication of the number of weights 19 if the weight is constant)), and the approximate amount of time needed to pickle until a certain degree of pickling is reached. It is also possible to provide means for displaying the required time. The container lid 5 may be made of a transparent material (for example, hard acrylic or glass).
A window made of the above-mentioned transparent material may be formed in a part of the window. Each of the weights 19 has a hollow outer shell made of the above-mentioned material such as plastic or stainless steel, and the hollow portion is filled with a material having a high specific gravity (such as sand, etc.).
It may also be formed by enclosing pebbles, iron balls, etc.).

(Embodiment 2) A second embodiment of this invention will be described below based on FIGS. In particular, the different configurations will be explained.

As shown in FIG. 3, in this embodiment, the container lid 5 is made of a hard resin material, and the opening 11 of the guide tube 10 is expanded in diameter and the seal ring 13 is attached to the opening 11 of the guide tube 10. Seal member 3 in place of
0 are integrally fitted. The sealing member 30 is formed from soft polyethylene resin into a cylindrical shape with both ends open, and has a cylindrical folded part 31 at one end.
have. In other words, when the seal member 30 is fitted into the opening 11, it forms a substantial opening 11a for the push rod 14. This sealing member 30 is connected to the guide tube 1.
0, that is, from the bottom side of the pickled vegetable container 1, is fitted into the opening 11a. Further, at the lower end side of the guide tube 10, a lower step portion 32 is formed by reducing the outer diameter. That is, when the seal member 30 is fitted, the folded portion 31 is integrally fitted to the stepped portion 32. In the embodiment, the guide tube 10 and the seal member 30
In order to achieve complete integration with the folded part 3,
1, a fitting groove 33 is formed along the circumferential direction on the folded side surface, and the fitting groove 33 is formed in the lower step part 32.
A convex portion 34 is formed to engage with the folded portion 3 to prevent the folded portion 31 from coming off.

Incidentally, seal portions 35 are integrally formed on the inner circumferential surface of the seal member 30 along the circumferential direction at positions on both end sides thereof. In terms of shape, when the push rod 14 is inserted and slid, the seal portion 35 elastically collapses in the sliding direction of the push rod 14.
It is formed in a pleated shape that can maintain a certain sealing function by slidingly contacting the push rod 14 and reducing the sliding resistance as much as possible. In other words, as shown in FIG. 4, the seal portion 35 has a triangular cross-section in the circumferential direction that is convex inward in the radial direction. It has a notch 36 for this purpose.

In addition, in order to obtain higher slidability and sealing performance with respect to the push rod 14, the sealing member 30 is installed in a fifth position.
It is also possible to form it as shown in the figure.

That is, a cylindrical sealing member 30a with both ends open is formed from a soft polyethylene resin, and at the same time the guide tube 10 is attached to both ends of this sealing member 30a.
The collar portions that are seated at both ends are integrally molded. Then, the inner surface of the sealing member 30a is bulged radially inward into a barrel shape and bent, and at the same time, the top of the bent portion is depressed radially outward into a groove shape.
Wavy seal portions 35a are formed at both ends of the seal member 30a, and an air buffer chamber 47 is formed between the seal member 30a and the inner surface 11 of the guide cylinder 10.

With this structure, when the push rod 14 slides, the seal portion 35 is cushioned by the air buffer chamber 47.
The sliding function of a is improved, and at the same time, the sealing performance against the push rod 14 is improved due to the reaction force caused by the change in volume of the air buffer chamber 47.

By the way, as shown in FIG.
In this embodiment, the diameter of the upper end of 4 is reduced to form a step, and a weight 38 having the shape shown in FIG. 7 is fitted and seated on the upper step 37. . This weight 38 is the same as that in the above-mentioned embodiment 1.
It is different in shape from the weight 19 of the weight 19, and has a cylindrical fitting part 39 at the bottom for fitting the stepped part of the push rod 14, so that the weight 19 has a cylindrical fitting part 39 in order to obtain an aesthetic appearance. It is becoming a state. These weights 38 and push rods 14 are made of a resin material with hollow interiors as shown in FIGS. 6 and 7, respectively, and are made to have a predetermined weight by filling the interior with sand or the like. is formed. For example, when using sand, the volume of each cavity is determined so that the weight of the push rod 14 is 3 to 4 kg and the weight of the weight is 6 to 7 kg. Note that openings 40 and 41 for sand injection are formed in the push rod 14 and the weight 38, respectively, and plugs 42 and 43 are provided in these openings 40 and 41, respectively, to completely seal them. In addition, when making miso sauce, Narazuke, eggplant, pickled cucumber, etc. in rice bran, it is not necessary to use the push rod 14 and the weight stone. For this reason, as shown in FIG.
4, and after removing the push rod 14 from the guide cylinder 10, a cup-shaped opening/closing plug 45 is removably screwed onto this male thread 44 to prevent odor from leaking out of the container 1. I try to do that. Further, when the seal member 30 having the seal portion 35 having a triangular cross section is used to attach the stopper 45, a gasket 46 is integrally attached to the bottom of the stopper 45.

Next, the operation of the second embodiment will be explained.

In FIGS. 3 to 5, the seal portions 35 and 35a provided on the inner surface of the guide tube 10 fall down along the sliding direction of the push rod 14 when the push rod 14 is raised and lowered, while maintaining a constant sealing ability. 14 to reduce the sliding resistance. As a result, insertion and removal of the push rod 14 becomes extremely easy. In addition, seal members 30, 30
a. By integrally forming the folded portion 31 and the sealing portions 35, 35a with a soft polyethylene resin as an elastic material, the cost can be significantly lower than that of the seal ring 13 due to the mass production effect.
Further, the push rod 14 in this embodiment is formed so as to function as a weight itself, and may be used in cases where a relatively low weight of weight is sufficient or after a certain period of time has elapsed, the weight of the weight may be reduced. In this case, it is possible to make pickles using the push rod 14 alone. In this embodiment, the above-mentioned pickle container 1 and container lid 5 are made of hard glass, and the push rod 14 and the weight are made of solid substitute stones to improve the design appearance, and when the weight is not used, It is also possible to configure it to be used as an ornament for a tea chest. However, in this case, the configuration using the seal ring 13 of the first embodiment is applied without using the seal member 30, and a grip part shaped like a bridge railing is formed at the upper part of the push rod 14. .

[Effects of the invention] As is clear from the above explanation, this invention provides the following excellent effects.

(1) The container lid can be easily engaged and disengaged from the pickles container with a small force, and leakage of odors generated inside the pickles container can be completely blocked.

(2) Sealing performance can be ensured while greatly reducing the sliding resistance of the push rod.

(3) Even when making accessories that do not require weights, odors can be prevented from leaking to the outside.
